One of the churches in the deanery has developed a new site - you may find it interesting to have a look. Certainly it intends to be a more "warts and all" exploration of child-friendly ministry than most comparable sites. Comments are welcome.
As for as I know, Peter's is the only other regularly-updated site operated by a member of a Chelmsford South deanery church - unless you count the official church sites, which exist mainly as advertising tools for the congregations concerned. If I've missed some interesting links, please do let me know.
